Abstract

See full text

A linear jack includes a coarse nut threadedly coupled to a first rotating screw and a first sleeve mounted to the coarse nut (the first rotating screw, the first sleeve, and the coarse nut collectively a high-speed assembly), and a second sleeve threadedly coupled to a second rotating screw (the second sleeve and the second rotating screw collectively a low-speed assembly). The coarse nut is configured to operate in a first mode where the coarse nut is held from rotating with the first rotating screw to convert rotational motion of the first rotating screw into translating motion of the coarse nut and the first sleeve. The coarse nut is configured to operate in a second mode where the coarse nut rotates with the first rotating screw so that only the low-speed assembly operates to extend the second sleeve.
